Among most water used for watering flowers, rainwater is better than other water, and rainwater is rootless water. Rainwater is water that nature absorbs from rivers, lakes and seas and falls again. Moreover, there are no impurities in the composition of rainwater, so using rainwater to water flowers is more conducive to the rooting and germination of flowers.

Disadvantages of watering flowers with rainwater

If too much rainwater is used to water the flowers, the moisture from the rain will fill the gaps in the soil, causing the air in the soil to be replaced by water, resulting in hypoxia. The root tissue will have difficulty breathing due to lack of oxygen, and its metabolic function will be reduced, and its absorption of water and fertilizer will be affected. If this continues for a long time, the flowers will suffocate and die.
